What mod chip do i have installed on my wii???

hello everyone after searching and searching for answers i still can not find what im looking for..i got this wii from my friend and he got it modded in colombia by some shop. the wii worked fine but now it does not play newer games. for example we insert super mario bros and we start it up and we get a black screen and freezes. he updated it and now it doesnt even read the disc at all but older backup games do play. so i figured open it up and see what chip it is but it doesnt have much info. maybe someone could tell me..the picture is blurry but this is what the chip says..
